Mexican President Andres Manuel Lopez Obrador suggested Mexico might be ready to step up migration control measures in response to President Donald Trump’s tariff ultimatum.

Lopez Obrador said Mexico could be ready to strike a deal with the United States by helping prevent illegal border crossings into the U.S. during a news conference, Reuters reported.

Mexican Foreign Minister Marcelo Ebrard is leading a delegation set to meet with U.S. officials in Washington, D.C., on Wednesday, and will attempt to reach an agreement over the border control issue.

Lopez Obrador said he expects “good results” from the negotiations, according to Reuters.

“The main thing is to inform about what we’re already doing on the migration issue, and if it’s necessary to reinforce these measures without violating human rights, we could be prepared to reach that deal,” Lopez Obrador said.

Trump announced Thursday his intention to place a 5% tariff on Mexican imports, starting June 10, until the issue of illegal immigration was addressed by the Mexican government.

On June 10th, the United States will impose a 5% Tariff on all goods coming into our Country from Mexico, until such time as illegal migrants coming through Mexico, and into our Country, STOP. The Tariff will gradually increase until the Illegal Immigration problem is remedied,..
